As we discovered when the OnePlus 2 was officially announced, the Type-C support boasted in the latest ‘flagship killer’ isn’t true Type-C support, the company has essentially just stuck a Type-C shaped connecter to the end of a regular Micro USB cable. During testing, Leung discovered that the OnePlus connector isn’t spec compliant, and although it does charge the Chromebook Pixel and other Type C devices, it doesn’t do so correctly.

The issue — it seems — is with the power management. Since the cable and Type C adapter use the wrong identifier resistor — which essentially means a true Type C product will try (and fail) to draw 3A power from the connector — it could cause damage to whatever it’s connected to. From the Amazon review of the Micro USB to Type-C adapter:

I found that this adapter does not correctly charge the Chromebook Pixel and other Type-C devices. My analysis shows that this cable, although will charge and provide data through to the devices, does not correctly follow the USB Type C specification for power delivery identification. The Oneplus adapter advertises itself as 3A capable, but that is not appropriate because this is a legacy host port adapter.

This warning comes as confirmation of what we already knew. The Type-C connector is only skin deep and doesn’t include any of the technological advantages that typically come with true Type-C products. In short: You should only use the OnePlus charging accessories with the OnePlus 2, and not with your new Nexus or any other future devices which ship with Type-C proper.
